I have personally seen & faced this situation 1st time to my friend & 2nd time 2 me. 1st time it was resolve only by changing the LNB's positions in Diseque switch but 2nd time I have to change the diseque because one of the IC which was controlling 4th LNB in my diseque fail due to some fault. So my recomendation to U is to change ur diseque switch

I have similar problem but little bit in different situation. One of the diseqc connection (asiasat3) to port 1 opposite to 4 is connected to another receiver via another port of Dual LNB (asiasat3). Now when I swithed off 2nd receiver (connected to asiasat3), 4th LNB work and I got signal in my 1st reciver. Any body can help me with this problem.+*pOther wise not!

Diseqc can only switch to one port at a time, so with 2nd receiver off, the 1st receiver can choose a port to switch to according to settings.

Possibly I dont understand you well, or, 1st receiver has a problem on switching one of the ports.
Two receivers demanding switching to different ports cannot work at the same time for the diseqc cannot do two ports but 1 at a time.
here is my setup

Your set up will work very well if AS3 has a dual output LNB, if single output shared then the demand on any first receiver on H polarity is supreme, then the next stb cannot get V polarity from AS3.
STB1 will work quite well on Optus, AS4 ku, AS4c - and finally AS3 if STB2 is off or voltage switching on STB2 switched off.

Yes that is the problem I mentioned in my previous post. AS3 dual LNB, and Optus D2 (port4) not working while STB2 switched on.

My question was, what is the problem and how to rectify? plz guide me.

I had changed my Diseqc switch with new, same problem.

Do find out some specs on your Dual output LNB, are the two outputs dependent or independent,What is the lnb separation on power feed, 22khz, polarities and signal path. There is a link in one of the factors on the lnb.
Another manufacturers Dual output lnb can also be tried out.
